i currently have flows welded into my stock setup. i am probably not going to do any major mods to my car.i would kinda like it louder. i was wondering if i could just get an x pipe and put that in if that would sound any louder? and can i just keep my stock pipes with that or do i have to get a full 2 1/2 inch cat back?

 

You can just change the mid pipe (i would suggest off road h with flows) and you can keep the same mufflers and tail pipes because thats what i did. But you might have a hell of a time removing the stock H with the mufflers right there in your way. might have to do some cutting and re welding
